    Finder 34.51.7.024.0010: ultra-slim 5 mm relay, sensitive 24 V DC coil 170 mW, 1CO AgNi 6 A 250 V AC, PCB or 93 series socket mounting.

  • Product description

    Ultra-slim relay | 24 V DC coil | 1CO (SPDT) | 6 A | 250 V AC | 5 mm | PCB | Finder 34.51 | 34.51.7.024.0010

    Finder 34.51.7.024.0010 is an ultra-slim electromechanical relay, just 5 mm wide, with a sensitive 24 V DC coil and one changeover contact rated 6 A / 250 V AC. It is soldered onto a printed circuit board or plugged into a Finder 93 series DIN rail socket.

    Key point:
    The sensitive 170 mW coil (7.1 mA) can be driven directly from a PLC or microcontroller output, while 6 kV insulation between coil and contacts separates the control side from the 230 V circuit. This is the standard slimline relay format widely used in industrial interfaces.

    Operating principle

    The relay is soldered onto a PCB (5 mm pitch) or plugged into a Finder 93.01 / 93.51 series socket mounted on a 35 mm DIN rail.

    When 24 V DC is applied to the coil (7.1 mA), the contact changes over: the common terminal connects to NO. The relay reliably operates from 16.8 V DC, and the coil tolerates up to 36 V DC.

    Result: minimal load on the control circuit and a galvanically isolated 6 A changeover contact.

    Why choose the Finder 34.51?
    5 mm width, a sensitive coil and 6 kV insulation – compact and safe separation of control and power circuits.

    Key functions

    • Sensitive 170 mW coil – driven directly from a PLC or microcontroller output.
    • 6 kV insulation – safe separation of control and 230 V circuits.
    • 5 mm width – high-density relay layout on a PCB or in a panel.
    • NO/NC changeover contact – switching on or off with a single relay.
    • AgNi contacts – suitable for power loads up to 6 A.

    Where is it used?

    • Controller and PLC output boards
    • Interface modules with Finder 93 series sockets
    • Spare relay for Finder 38 / 93 series modules
    • Heating, ventilation and air-conditioning controllers
    • Household appliance and device electronics
    • Alarm and building automation systems

    Use by need

    For electronics designers.
    Standard 5 mm relay format with a sensitive coil for PCB designs.
    For maintenance electricians.
    Spare relay for Finder 93 series sockets – replaced without disconnecting wires.
    For automation integrators.
    Combined with a 93.01 socket, it forms a slim 6.2 mm DIN rail interface module.

    Practical application

    If the relay in a Finder 93.01 socket has stopped switching the pump control, pull out the old relay and insert a new 34.51.7.024.0010 – the socket and wiring stay in place, and the system is running again within minutes.

    Pros

    • Only 5 mm wide
    • Sensitive 170 mW coil
    • 6 kV insulation between coil and contacts
    • Operating temperature from -40 to +85 °C
    • Suitable for PCB and 93 series sockets
    • Genuine Finder product

    Cons / limitations

    • Cannot be mounted on a DIN rail without a socket
    • No LED indication – provided by 93 series sockets
    • One changeover contact, up to 6 A

    Safety and installation notes

    • Disconnect the power before installing or replacing the relay.
    • Coil voltage is 24 V DC (up to 36 V DC permissible).
    • When soldering, follow the temperature profile specified by the manufacturer.
    • Do not exceed the 6 A / 250 V AC contact rating.
    • Installation must be carried out by a qualified electrician or electronics specialist.

    Suitable when you need to:
    • use a 5 mm relay on a PCB or in an interface module
    • replace a relay in a Finder 93 series socket
    • drive it from a PLC or microcontroller without an extra amplifier
    Check before use:
    • control voltage – 24 V DC
    • whether the socket accepts a 34 series relay
    • load current and voltage
    Important reminder: A relay is not a protective device – it does not protect against overload or short circuit.
